@@@@Based on the conventional observation data and numerical forecast products,in terms of the synoptic principle and the dynamic diagnosis,the first time strong rain and snow process in Beijing during 3-4 Novem?ber 2012 has been analyzed. The results showed that:At 500hPa the cold vortex is the principal effects of sys?tem;at 700hPa the southeast water vapor stream and cold air’s intersection,the frontal cyclone on the ground’s induced provide favorable dynamic conditions and moisture conditions for the conversion between rain and snow.
